Re: [Elecraft] K3 Beta Release: APF for CW; Fast Monitor improved TX gate for voice modes
Yes APF came out reel good, very well done! Don´t even know if it was this good on the FT-1000D, at least not on the units I did own. Now if only AM RX was to be fixed I would be happy, as it is right now AM (not sync AM) RX is more or less useless. It got broken in the DSP code way back. I have written about this problem before and I´m not going to repeat myself any further. / Jim SM2EKM - On 2010-11-04 00:17, Bill [NS4C] wrote: I loaded the beta firmware so I could see what all the APF buzz was about. 3D2A was spotted on 18070 so I turned the beam and he was there in and out of my noise level.

Re: [Elecraft] K3 APF FINE Tuning
This occurs in running in a contest, where you have positioned the hard skirts of roofing and regular DSP, to keep out the strong stations just above and just below. A weak station down in the noise calls you slightly up or down, but not out of your running passband. If you tune the RX frequency up or down to bring him into a fixed center passband APF, then you let one of the strong stations up or down under the roofing filter and it will start pumping AGC and trash the weak signal. Tuning on the APF and tuning its obvious audio center up or down, without moving the RX frequency, to the remembered frequency of the weak signal, peaks him right up without letting the up and down QRM under the roofing filter. Also it is easier to remember the audio tone of the weak signal if it fades and move the APF peak, than tune the RX and hold the audio peak constant. Unless you know in your head that you have only tuned 70 Hz of the 110 off frequency, and have a calibrated feel to the knob, you can't move the RX and APF peak to where the station was when it sank under the noise. 73, Guy.

Re: [Elecraft] K3 Transverter / 2m unit
Adriana Lexa - I have both the external XV144 and the internal K144XV. While they both have their advantages and disadvantages it all depends on what you want to use them for. For frequency stability the XV144 (with crystal oven) is far superior although Elecraft are currently doing some work towards reducing the drift in the K144XV. The internal transverter is fine for FM but I am finding the frequency drift of mine is unacceptable for CW or SSB unless your overs are very short. I understand that Elecraft are planning to provide a facility to lock the oscillator of the K144XV to that of the K3 which will cure the drift problem. To sum up, as things are at present, it's the XV144 for performance but the K144XV for convenience. 73 de David G4DMP In a recent message, Alexandr Kobranov kobra...@amoscz.cz writes As I am now to decide to buy K144XV or stay with some external - let me ask here: What is thermal stability of internal 116/118MHz Xtal osc?

Their implementation of APF is really an Audio Passband filter, rather than an Audio Peaking Filter. When engaged, their APF filter skirt is really no different than selecting a narrow DSP setting where there's a flat top and sharp skirts. The response curve does not resemble that of an audio peaking filter. I found the APF to be of limited value on the 7800 and 7700 transceivers.

Re: [Elecraft] [K2] Question about tuning K2 for SSB..
John, A 20 Hz mis-tuning of a SSB signal usually will not be noticed, 50 Hz maybe, and 100 Hz definitely. So yes, you would normally tune the station until it 'sounds right' and then transmit. That assumes that you are using the same filter for transmit and receive. You can make some trials with tests made with another ham who knows how you should sound. Move the filter passband up or down in 25 Hz increments to see if you have achieved a more suitable position for your voice. 73, Don W3FPR On 11/3/2010 10:20 PM, VK7JB wrote: Hi All, I'm learning to drive my new K2/100 and have reached a conceptual block that will betray a fundamental lack of understanding, but here goes anyway... My K2 dial frequency reads about 20hz under the actual frequency - receiving WWV on 1.00, the LCD frequency readout reads .98. That's all good. But, when I'm working SSB and want to make contact with a station already transmitting on a particular frequency, how do I handle the tuning to ensure I'm transmitting on his frequency exactly. Do I tune my K2 to achieve best resolved audio receiving his signal, regardless of the actual frequency displayed on my LCD, then assume when I hit TX I'll be transmitting exactly on his frequency? Or is there any other way to account for this small 20hz shift, to make sure I'm transmitting exactly where he is tuned? I'm running my K2 with the MH-2 mic and last night got reports of muffled audio. I suspect I'll need to tweak the SSB filter passband position- the position looks good on Spectrogram with the low frequency roll off for the SSB Tx filter sitting around 300hz, but I understand it may need some optimising with live audio monitoring. I did wonder if my tuning technique was contributing to the problem - perhaps I'm not transmitting exactly where they're listening. I hope that makes sense.

[Elecraft] APF Results at an Old Timer's shack
Well, I just wasn't sure I would use it, I had such good results with just the DUAL PB function. So I sought out the weakest signal I could find this morning, R5ZZ, who was not copiable here, but I could hear some Ws working him. I dialed in the APF and there he was, and copiable. So mea culpa.

Re: [Elecraft] APF Results at an Old Timer's shack
To this old dog's ears there is way too much ringing. Even in my EME days I never felt the need for these super narrow filters. I used a passive 200 Hz wide filter centered on 600 Hz. A few hours of listening to noise in a too-narrow filter and you start hearing things that aren't there, especially with some distortion thrown in, and ringing is distortion. Today I prefer a lower beat note (~450 Hz) and a couple of hundred Hz BW is fine most of the time.

Re: [Elecraft] APF Results at an Old Timer's shack
There was a suggestion posted within the last few days to reduce the ring by adjusting the APF SHIFT along with RIT by 20 Hz. This might make a nice one--push macro but I don't think there is a APF SHIFT command available yet (The IF SHIFT command does not work in APF.) Also, for for those who want less ringing you can try a wider WIDTH. If your CW bandwidth is typically set at 500 Hz or less try opeining the WIDTH to 1-2 KHz when using APF, if the conditions permit. 73, Drew AF2Z On Thu, 04 Nov 2010 11:32:53 -0400, Greg - AB7R wrote: I don't see this as something that would be left on ALL the time.

Re: [Elecraft] APF Results at an Old Timer's shack
For this old dog it is great ! I very much like the peak, works very well at pulling the weak signal up for much better copy. Congratulations Elecraft this is a super tool for CW ! Now the bad news. My Yaesu FT1000 was switched in when needed on CW receive just for the APF to pull a borderline CW signal up out of the mud. Looks like he will not be needed anymore. You have been a great radio FT1000 (sniff, sniff ) 73, Bob K6UJ On Nov 4, 2010, at 7:57 AM, Wes Stewart wrote: To this old dog's ears there is way too much ringing.

Re: [Elecraft] APF Results at an Old Timer's shack
This method does diminish the ringing -- offsetting the APF peak using SHIFT and the receive frequency using RIT. 20 Hz seems to be about right, too. The bad ringing only occurs when the peak frequency and the center of the passband coincide exactly. I had a lot of fun this morning, right after installing the new firmware, listening in on a guy in 9-land running JAs on 40 CW, tuning in the weaker JAs with the APF shift inside the 200 Hz IF passband. Really cool. Being able to tune the peak in 5-Hz increments will be especially cool, so I'm looking forward to the next update. Whether you respond positively or negatively to the characteristics of a narrow passband seems to be a very individual thing. I've even heard guys say they prefer to copy CW in a wide-open SSB width passband, filtering out QRM only with their wetware. Been there, done that. I cut my eye-teeth as a Novice in the early 1960s doing this because I didn't have any other choice; my cheap-o NC-60 receiver didn't have any selectivity to speak of. But I began to appreciate selectivity as soon as I started experiencing it, and since then, it's been the more the better. I love the new APF! It reminds me of how the peak function in the old Heathkit QF-1 Q-Multiplier used to work and sound, except it's even better.

[Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
I updated my K3 to MCU 4.17 beta last night along with DSP 2.65 and FPU 1.4(?) and now today I notice that my SSB output is down about 3 dB. I can only coax about 50 Watts peak out of it and I've made no changes to microphone, TX EQ, Mic Gain, Compression, or output power (set to 100 W). CONFIG:TXG VCE is set to 1.0 dB as before. On CW I get a full 100 Watts peak. Anyone else seeing this? 73, de Nate -- The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true.

Re: [Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
Additional testing shows that when I set my power down to 5 Watts and then back up to 100 Watts results in a max peak output of 50 Watts on SSB on both an external and the K3's Wattmeter. Setting the mode to CW results in 100 Watts output and reverting back to SSB I can get about 75 Watts peak on both meters. 73, de Nate -- The optimist proclaims that we live in the best of all possible worlds.

Re: [Elecraft] APF Results at an Old Timer's shack
Greg, I agree 100% It is a tool and is there for the specific use of pulling a weak CW signal up out of the mud so you can copy him. Turn on when needed. The Yaesu FT1000's, early issues, had great APF and had a little ringing but they worked very well, the little ringing goes with the territory with the sharp peaking. You didn't leave them on all the time, really worked well when needed. Then Yaesu responded to the issue of the ringing and in later versions the ringing was gone but the peaking was reduced and APF wasn't very effective. Then. mods came out to restore the previous peaking effectiveness, (and slight ringing) hi,hi. I don't know how to best describe it but it is a sharp CW listening experience. There are other tools on the K3, narrow filters, etc that we use for improved copy on CW signals and the APF is another for really digging in (when needed) Bob K6UJ On Nov 4, 2010, at 8:32 AM, Greg - AB7R wrote: I don't see this as something that would be left on ALL the time.

[Elecraft] APF Macros
I received some helpful suggestions from The Smiths regarding APF, specifically using RIT to shift the received signal down 20 Hz or so and using APF Shift to peak the signal. The purpose is to make the tone of the received signal 20 Hz lower than the faint ringing noise induced by APF. This seems to work pretty well, and I used the technique to copy some weak signals on Top Band last night. Since the technique requires a bit of knob fiddling, I decided to try to incorporate these steps into a K3 Macro. So far, I've been able to put all the steps except the APF Shift into a Macro. I tried using the IS command to do APF shift (after turning on the APF); however the command continues to shift the IF rather than the APF. \ Is there a special command available yet for APF shift, or is this too soon to have something because APF is still in Beta testing? Here's what I have so far: APF SHFT IS ;SWH29;RT1;RD;RD;SWT49; IS centers IF shift to cw pitch; SWH29 turns on the APF; RT1 turns on the RIT; the RD commands move RIT down 20 Hz, assuming the user has the normal 10 Hz tuning steps setup; and SWT49 engages FINE tuning. To undo all this I have: APF CLR SWH29;SWT49;RU;RU;RT0;IS ; I'm open to suggestions for improvement. 73, Chuck Guenther NI0C K3 s/n 1061 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
I went through the CONFIG menus to see what might have changed while in SSB. I found DUAL PB had APF on. I was unable to turn it off while in SSB, so went back to CW mode turned the APF off (nor) and returned to SSB and all was normal. Full output. I have confirmed you can only turn APF on/off while in CW mode. It would then seem that APF should be turned off automatically when in any mode other than CW.

Power fine here with 4.17. Get full 100W PEP out on both CW and SSB and the drive power that I normally use for my amp is as accurate as it always was. Checked two K3s with an Alpha 4510, an LP-100A and an Array Solutions PowerMaster.

Re: [Elecraft] XV-144 Stability
Yes, Eric, like you I usually switch on my XV144 for about 20 minutes before I intend to use it to allow the crystal oven to get up to temperature. Then, it is nice and stable. I did have the Mitsubishi PA module fail on me and had to replace it. I have also fitted an internal fan similar to that used in the XV432. Since then, no problems. In contrast, my internal K144XV drifts almost 100Hz in five minutes, even after allowing 30 minutes to 'warm up'. 73 de David G4DMP In a recent message, Eric gliderboy1...@yahoo.com writes I use an xv-144 for jt65 eme.

Re: [Elecraft] Firmware load
Remove power connector from K3. If a P3 is inline, remove P3 power connector so that P3 will not power up, even for a moment, when you reapply K3 power. Reboot PC. This isn't often necessary, but sometimes a COM port or USB driver is in an awkward state. If you don't reboot, do stop the K3 Utility. Plug K3 power connector back in. Press K3 power button. Expect to see MCU LD in an otherwise LCD. Start k3 utility. Navigate to Port tab. Wait until it connects, expect a warning popup about finding a K3 in boot loader. Select firmware tab and select send all firmware. I do this a lot, I think my K3 and Waynes and Lyles get more firmware loads than most. It's not extraordinary. 73 de Dick.

Re: [Elecraft] Firmware load
Jim needs to fill us in on what is running. I have all equipment plugged in. I have the works. The W2 requires a second RS232 or remove from one external device and move to another. If that is being done then there are other things to consider. (This is where internal USB converters can make a difference if programmed into firmware so those not so blessed with computer skills will benefit.) I find that either one of two com ports are used. If you move the connector and a comport isn't released, then a reboot might help. I have a W2, P3, Kx144, P3 and the obvious K3. I also use a THP HL-2.5kfx which uses another interface. I don't have the same issues he experiences. From what I understood from his message is that the program isn't correctly loading to his desktop. I could be wrong, won't be the first time :-).

[Elecraft] K2/10 SN#543 Lower Po on 15/17M
Hi Gang, During my last contest foray, I noticed that making Qs on 15M was difficult. Turns out that with only about 50mW, it is! And 17M is likewise low. The rest of the radio is FB. Also, the current draw on 15/17 is basically the same in RX and XMIT.(My Astron's meter moves about one needle width.) The Power Control has no effect on the 15/17 power levels. I am hoping that there is some common problem that I can easily fix. Can anyone point me in the right direction? I have an RF probe so I can trace the signal to look for loss. Would be nice to start close to the expected problem area. 73, Mark K2QO FN03ra [image: Nuclear Power Yes Please (128x128).png] __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
I am seeing the same reduction in SSB output power. I installed 4.17 Beta last night. It appears that the reduced power only occurs when I have APF activated. I have twice restored SSB power by doing the following: 1). Changing mode back to CW, 2). Going to Dual PB in Config menu and turning APF off, 3). exiting Config menu, 4). changing mode back to SSB. Power is restored back to a full 100 watts. With APF set to on, SSB power is reduced to about 70 watts. I confirmed this on 17M by repeating the process twice, and I then tried 20 M SSB and the power was back to 70 watts (after I had turned APF back on.) Is this a problem with the beta release? I saw Wayne's suggestion to do a TX gain calibration, but it seems strange that I would only need to do this after installing Beta 4.17. APF works great, but I need to resolve this SSB power issue.

Re: [Elecraft] [K2] Filters attenuation
Yes, mine attenuates but haven't bothered to measure it. Strangely, the 700 Hz seems worse than the narrower filters. Curt KB5JO I dunno about the loss you are seeing but I've measured about 8 dB of loss in my K2 at 200 Hz vs 1 kHz BW. That does strike me a quite a bit of loss. I just don't use the narrow filters often. I know of at least one other K2 that has similar loss.

[Elecraft] APF and audio limiting
I'm playing with the new APF, and trying to get a REALLY weak QSO to pop. I have the volume cranked up pretty good, and a REALLY strong station throws in their call. I thought my speakers had blown.

Re: [Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
Now I seem to have a real problem. I did a TX Gain calibration using the K3 Utility for both 5 and 50 watts. I worked perfectly and tx gain appeared to be right on all bands. I then did some testing into a dummy load with RTTY. I noticed that power would start out at 25 watts and it would take several transmissions to get it up to 70 to 100 watts. So I decided to do a wattmeter calibration. I had selected WMTR LP and was attempting to do the 5.0 W calibration into a dummy load. But I could not get the output power to change much and after several tries I got a high current reading. Now I can get audio only out of the left side of headphones and when I attempt to reselect the WTMR parameter it is no longer there. The selection in Config skips from VFO OFS to XVn ON. I assume I have blown something out. However, I am considering reverting back to MCU version 4.14. Any other suggestions? Thanks in advance.

Re: [Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
OK, my SSB output was low too. I'm on phone so rarely, were it not for the reflector, I'd probably never have checked and when I did find out, the thread would have already died. I did the TX Gain calibration as Wayne suggested, all seems to be well on all bands. Apparently, the DL in my MFJ tuner isn't all that 50 ohms-ish on 6m, but the trusty Heath Cantenna is. The APF feature is really quite amazing. I have to miss SS CW, family stuff, but I'm anxious to try it out for real. It already got me 9U0A, he was whisper weak, maybe S[minus]1, I got 9A and wondered why the pileup on a 9A? APF in, he sounded S5. S-meter was still on the peg however. 73, Fred K6DGW - Northern California Contest Club - CU in the 2011 Cal QSO Party 1-2 Oct 2011 - www.cqp.org On 11/4/2010 10:32 AM, Nate Bargmann wrote: Additional testing shows that when I set my power down to 5 Watts and then back up to 100 Watts results in a max peak output of 50 Watts on SSB on both an external and the K3's Wattmeter.

Re: [Elecraft] [K2] Question about tuning K2 for SSB..
You can adjust the ssb filter by listening to your own voice on the rig and adjusting the ssb filter to what sounds best to you. To monitor your own voice set the SSBA option to BAL. Then got to CAL FIL for the filter you want to adjust and adjust it (a little at a time) while talking into the mic. The only caveat is that your mic has to be hot (making a signal) when the PTT line is *not* active. If your mic opens the mic signal line when PTT is not pressed you will have to temporarily jump out the switch contact that opens that signal. I found it was better if someone else was listening to my voice on the headphones instead of myself. They'll let you know when you have adjusted the ssb filter for the best audio. Don't forget to reset the SSBA BAL option back to its previous value after you're done. Sounds harder than it is. You can probably do the whole thing in 1/2 hour.

My K2 dial frequency reads about 20hz under the actual frequency - receiving WWV on 1.00, the LCD frequency readout reads .98. That's all good. But, when I'm working SSB and want to make contact with a station already transmitting on a particular frequency, how do I handle the tuning to ensure I'm transmitting on his frequency exactly. Do I tune my K2 to achieve best resolved audio receiving his signal, regardless of the actual frequency displayed on my LCD, then assume when I hit TX I'll be transmitting exactly on his frequency? Or is there any other way to account for this small 20hz shift, to make sure I'm transmitting exactly where he is tuned? I'm running my K2 with the MH-2 mic and last night got reports of muffled audio. I suspect I'll need to tweak the SSB filter passband position- the position looks good on Spectrogram with the low frequency roll off for the SSB Tx filter sitting around 300hz, but I understand it may need some optimising with live audio monitoring. I did wonder if my tuning technique was contributing to the problem - perhaps I'm not transmitting exactly where they're listening. I hope that makes sense.

Re: [Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
Same thing to me, I was noticed it when put my Amp w/GU84B on, need 20w+ to obtain 500w in ssb instead of my normal 16w.

When download back the 4.14, everything returns to normal. I have download again the 4.17 and same problem occurs but let it like this the time a solution will be available on line.
